VALVE AND. COCK.

To all whomtt concern.-

' Be it known that I, ALFRED WILLIAMS, a subject" of the King of Great Britain,'residcounty of London, England, have invented and Cocks, of which the following is a specification.

This invention which relates to valves and cocks for controlling the flow of liquids and other purposes, has for its objects to reduce the cost of production of such valves. and

- cocks and to insure a steady flow of liquid from the same. I accom llSh these objects by the mechanism shown y the accompanying drawin -.in which v Figure 1 1s an elevation of a valve for. do-

mest1c water supply constructed according to this invention. I ig. 2 is a longitudinal section of the same. Fig. 3 is an elevation of the cap detached from the bod of the valve. Fig. 4 showsdevelopment o the slot on a plane surface. Fi 5 is anelevation 'of one form of detachab je bib or nozzle -constructed according to this, invention. Fig. 6

is an elevation of another form of .bib 0r nozzle also constructed according to this invention. 7 shows the water regulator.

ongitudinal section of afloat -va veconstructed according to thisinvention, with a horizontal lun er; Fig. 9 is a v longitudinal section o a oatyvalve conwith a vertical of the same. I Similar letters refer to" similar parts throughout the several views.

e' is a cage made integral with the cap I) and is provided with an inclined slot f showndeveloped by Fig. 4,v and with an ap erture g facing'the outlet h. I z' is the inlet for the fluid.

In order to avoid the expense andtrouble attendant on the screw for opening andclosling thevalve and the leat er; washer for makin the joint I employ a valve stem j furnis ed with a knob cross or other convenient means for rotating the same is at the top and a cup Z at the bottom, the stem j be- Specification of Letters Patent.

ing fitted with a'screw pin m which engages .with the slot f which screw when the stem is rotated causes the stem to move vertically.

n is the valve seating which is made cupshaped to receive the ball 0, the seating ,n

and the cup in the bottom of the stem bein of greater radius than the radius of the ba 1 o to prevent the ball from sticking in either. ofthecups I The horizontal portions of the slot f hold the valve full open or completel closed, intermediate positions being 0 tained by means of the inclined portions of the slot.

The ball 0 ma be made of metal, vulcanite, vulcanized fi er, soft india rubber, or of any other suitable material; .for example steam valves and spirit valves may have Patented July 12, 1910. I

metal balls, hot water, valves would have rubber or vulcanized fiber balls, and cold water valves would have soft rubber balls. Valves for acids would have the body, cap,

ball and stem made of vulcanite as usual, or

the body and cap might be made of pottery ware.

for a valve or cook with a long bib, another pattern for a valveor cock with a short bib and so on, I make the bibs or nozzles pdetachable from the body of the valve or cock so that the valve or cock maker need have a stock of only one'pattern of body per unit of size the cocks or valves cast from this pattern being fitted with any size and shape of bib required by the customer.

4 As will be'seen byinspection of Figs. 1, 2

and 5' the bibsare made to screw on to the outlet portion of the body of the cock or valve.. Figs. 1 and 2 show the valve. or cock fitted with a short bib. Fig. 5 showsa long bib detached from the body of a'cock -or valve and Fig. 6 shows a detachable bib furnished with .a screw thread to receive a hose or other coupling. To regulate the flow of water or other liquid according to the pressure of the liquid entering the valve or-cock so 'as to enable the liquid issue from the mouth of the bib in a solid jet, I place a cone 9 in the bib, the conev being held between the end of the outlet of the body and the shoulder r of the bib 72. The taper of the cone depends upon the pressure of the fluid entering the valve or cock, the higher p In order to reduce the cost of production, I

instead of having to make a special pattern cone and vice-versa. The cap b is secured to the body a by means of screws w.

' Figs. 8 to 10 show my invention applied to float valves ofvarious kinds, Fig. 8 s owing the ball'o actuatedby a horizontal plunger 8 and abell-crank lever t which is attached to the float u. The plunger 8 is made conical or conoidal, the inner end having a cup u formed therein of greater radius than the radius of the ball 0, the outer end of the plunger engaging with a cup or depression 111 the lever t. Figs; 9 and 10 show a float valve with the plunger vertical.

My invention of detachable bibs and water 7 regulators may be applied to cocks with rotating plugs.

Valves and cooks constructed according to this invention may be made of any suitable material to enable them to be used for steam,

water, tar, acids, and other fluids.
